George Ciordas-Hertel is a doctoral researcher at the Educational Technologies group of the DIPF | Leibniz Institute for Research and Information in Education, based in Frankfurt am Main (Germany). He started his career as a software engineer in 2010 working for a network infrastructure provider. There he worked on various software products related to web services and assistance through AI. In November 2017 he got accepted as a doctoral researcher at the DIPF on the topic of Trusted Multimodal Learning Analytics Infrastructures. His current research focuses on mobile sensing of students' physical context with smart wearables. Here, he uses AI techniques to assess the effects of the physical context on learning and the learner. In addition, he is concerned with the data protection requirements of these methods.
